Pathogens promote matrilocal family ties and the copying of foreign religions.Lei Chang,Hui Jing Lu &Bao Pei Wu -2012 -Behavioral and Brain Sciences 35 (2):82-83.detailsWithin the same pathogen-stress framework as proposed by Fincher & Thornhill (F&T), we argue further that pathogen stress promotes matrilocal rather than patrilocal family ties which, in turn, slow down the process of modernity; and that pathogen stress promotes social learning or copying, including the adoption of foreign religions.
Enhancement of Event-Related Desynchronization in Motor Imagery Based on Transcranial Electrical Stimulation.Jiaxin Xie,Maoqin Peng,Jingqing Lu,Chao Xiao,Xin Zong,Manqing Wang,Dongrui Gao,Yun Qin &Tiejun Liu -2021 -Frontiers in Human Neuroscience 15.detailsDue to the individual differences controlling brain-computer interfaces, the applicability and accuracy of BCIs based on motor imagery are limited. To improve the performance of BCIs, this article examined the effect of transcranial electrical stimulation on brain activity during MI. This article designed an experimental paradigm that combines tES and MI and examined the effects of tES based on the measurements of electroencephalogram features in MI processing, including the power spectral density and dynamic event-related desynchronization. Finally, we investigated the effect (...) of tES on the accuracy of MI classification using linear discriminant analysis. The results showed that the ERD of the μ and β rhythms in the left-hand MI task was enhanced after electrical stimulation with a significant effect in the tDCS group. The average classification accuracy of the transcranial alternating current stimulation group and transcranial direct current stimulation group were improved significantly compared to the pre-and pseudo stimulation groups. These findings indicated that tES can improve the performance and applicability of BCI and that tDCS was a potential approach in regulating brain activity and enhancing valid features during noninvasive MI-BCI processing.

Family Related Variables’ Influences on Adolescents’ Health Based on Health Behaviour in School-Aged Children Database, an AI-Assisted Scoping Review, and Narrative Synthesis.Yi Huang,Michaela Procházková,Jinjin Lu,Abanoub Riad &Petr Macek -2022 -Frontiers in Psychology 13.detailsObjectsHealth Behaviours in School-aged Children is an international survey programme aiming to investigate adolescents’ health behaviours, subjective perception of health status, wellbeing, and the related contextual information. Our scoping review aimed to synthesise the evidence from HBSC about the relationship between family environmental contributors and adolescents’ health-related outcomes.MethodsWe searched previous studies from six electronic databases. Two researchers identified the qualified publications independently by abstract and full-text screening with the assistance of an NLP-based AI instrument, ASReview. Publications were included if they (...) were based on HBSC data and investigated the effects of family environment on adolescents’ health outcomes. Researches addressed family-related factors as mediators or moderators were also included.ResultsA total of 241 articles were included. Family environmental contributors could be mapped into six categories: Demographic backgrounds ; General family’s psycho-socio functions ; Parenting behaviours ; Parental health behaviours ; Family activities ; and Siblings. Except for 75 papers that assessed family variables as moderators and mediators, the others suggested family environment was an independent variable. Only five studies employed the data-driven approach.ConclusionOur results suggest most research studies focussed on the influences of family demographic backgrounds on adolescents’ health. The researches related to parental health behaviours and siblings are most inadequate. Besides, we recommend further research studies to focus on the mediator/moderator roles of the family, for exploring the deep mechanism of the family’s impacts. Also, it would be valuable to consider data-driven analysis more in the future, as HBSC has mass variables and data. (shrink)
Impact of Postgraduate Student Internships During the COVID-19 Pandemic in China.Wenyi Zhang,Xiaozhong Lu,Derong Kang &Jiaxin Quan -2022 -Frontiers in Psychology 12.detailsTo understand the impact of the COVID-19 pandemic on postgraduate students’ internships in China, 911 students from different regions of China were surveyed through online questionnaires. Among the postgraduate students surveyed, 48.51% of which believed that the pandemic had its greatest impact on colleagues interaction, and 59.60% believed that the pandemic had a strong impact on practical skills. In total, 31.8% of postgraduate internship programs were impacted by COVID-19. The proportions of respondents having severe, moderate, and mild anxiety levels were (...) 1.42%, 4.72%, and 15.92%, respectively; and the rates of severe, moderate, and mild depression were 1.64%, 10.86%, and 21.84%, respectively. ANOVA found that major, degree type, and degree of impact of the pandemic on colleague interactions and improved practical abilities all affected postgraduate mental health. The findings suggest that the mental health of postgraduate students should be monitored during a pandemic, and targeted psychological counseling should be offered. Postgraduate internships should be emphasized as to ensure a smooth internship process during a pandemic period. Psychological counseling and assistance should be provided to those whose internships were affected by the pandemic, and programs should be set up to aid postgraduate students in adapting to the new internship and employment conditions brought on by the “new normal” of pandemic prevention and control.

Invulnerability Analysis and Optimization Strategy of Sector Network Using Cascading Failure Model.Haijun Liang,Jingyu Lu &Nan Chen -2022 -Complexity 2022:1-12.detailsResolving the challenge of flight delays caused by air traffic congestion renders it necessary to explore the mode of congestion propagation. By applying complex network theory, this article establishes a complex network structure where airspace sectors act as nodes, and the edges represent traffic flow relationships between sectors. In addition, a cascading failure model is proposed to analyze the airspace sector network’s invulnerability. The critical threshold and the sector abnormality rate are determined according to the cascading failure measurement indexes. Based (...) on the remaining capacity of sector nodes, two optimization strategies are proposed: adjacent load redistribution strategy and local load redistribution strategy. The simulation results demonstrate that the local load redistribution strategy greatly improves the airspace sector network’s invulnerability to cascading failure. (shrink)
Institutional Environment and Green Economic Growth in China.Xiaoxiao Zhou,Lu Wang &Juntao Du -2021 -Complexity 2021:1-10.detailsAs the answer to sustainability concerns, green economic growth has gradually attracted considerable attention. Notably, the optimization of the institutional environment contributes to green economic growth from the perspective of new institutional economics. However, few studies have systematically explained the connection between the institutional environment and green growth. In this study, the institutional environment was divided into three dimensions: governmental, legal, and cultural subenvironments. We adopted econometric models with the effect of every dimension on green growth and empirically analyzed with (...) the generalized method of moments, based on Chinese provincial panel data from the years 2000–2016. The results indicated that there was an inverted U-shaped relationship between China’s institutional environment and its green growth. That is, the institutional environment can initially promote China’s green growth but, if it is not changed, will eventually inhibit it. In addition, the analysis on the three dimensions of the institutional environment highlighted that the role of the cultural subenvironment in green growth is greater than those of the governmental and legal subenvironments.

A total of 2,116 participants on the Chinese mainland completed the online survey. We employed exploratory factor analysis and confirmatory factor analysis to investigate the factor structure. The findings showed that the one-factor model of the CAS Chinese version fitted perfectly with the data. The multigroup CFAs showed the measurement invariance across gender and age groups. We also examined the CAS’s (...) internal consistency and convergent and concurrent validity. The results demonstrated that the one-factor model had good reliability and convergent and concurrent validity. Overall, according to our findings, the CAS Chinese version was reliable for measuring coronavirus anxiety during the COVID-19 delta outbreak. (shrink)
Effects of Ordered Grasping Movement on Brain Function in the Performance Virtual Reality Task: A Near-Infrared Spectroscopy Study.Xiangyang Li,Jiahui Yin,Huiyuan Li,Gongcheng Xu,Congcong Huo,Hui Xie,Wenhao Li,Jizhong Liu &Zengyong Li -2022 -Frontiers in Human Neuroscience 16.detailsObjectiveVirtual reality grasping exercise training helps patients participate actively in their recovery and is a critical approach to the rehabilitation of hand dysfunction. This study aimed to explore the effects of active participation and VR grasping on brain function combined with the kinematic information obtained during VR exercises.MethodsThe cerebral oxygenation signals of the prefrontal cortex, the motor cortex, and the occipital cortex were measured by functional near-infrared spectroscopy in 18 young people during the resting state, grasping movements, and VR grasping (...) movements. The EPPlus plug-in was used to collect the hand motion data during simulated interactive grasping. The wavelet amplitude of each cerebral cortex and the wavelet phase coherence of each pair of channels were calculated by wavelet analysis. The total difference in acceleration difference of the hand in the VR grasping movements was calculated to acquire kinematic characteristics. The cortical activation and brain functional connectivity of each brain region were compared and analyzed, and a significant correlation was found between VR grasping movements and brain region activation.ResultsCompared with the resting state, the WA values of LPFC, RPFC, LMC, RMC, and ROC increased during the grasping movements and the VR grasping movements, these changes were significant in LPFC and LMC. The WA values of LMC in the VR grasping movements were significantly higher than those in the grasping movements. The WPCO of the cerebral cortex increased during grasping exercise compared with the resting state. Nevertheless, the number of significant functional connections during VR grasping decreased significantly, and only the WPCO strength between the LPFC and LMC was enhanced. The increased WA of the LPFC, RPFC, LMC, and RMC during VR grasping movements compared with the resting state showed a significant negative correlation with KCs.ConclusionThe VR grasping movements can improve the activation and FC intensity of the ipsilateral brain region, inhibit the FC of the contralateral brain region, and reduce the quantity of brain resources allocated to the task. Thus, ordered grasping exercises can enhance active participation in rehabilitation and help to improve brain function. (shrink)
